。[Scope of claims for utility model registration] (1) Nozzle 1 provided at the tip of processing head 1
In a laser processing machine that cuts the workpiece 3 by irradiating a laser beam 2 toward the workpiece 3 to be cut from a point a and simultaneously ejecting assist gas, the pressure of the assist gas in the processing head 1 is detected, and the assist gas pressure in the processing head 1 is detected. The detected value is compared with the pressure setting value for cutting set in advance with the pressure setting device 11, and the pressure regulating valve 6 is controlled so that they match, and the assist gas pressure in the machining head 1 after cutting is set to atmospheric pressure. An assist gas control device for laser processing machines that maintains a slightly higher pressure. (2) When switching the assist gas pressure in the machining head 1 from cutting to non-cutting, the assist gas pressure is gradually lowered, and when switching from non-cutting to cutting, it is controlled so that it instantly increases to the cutting pressure. The assist gas control device according to claim 1, wherein the assist gas control device comprises:
